IMPROVEMENT IN BUILDING-BLOCKS.

Specification forming part of Letters Patent No. 144,149, dated October 18, 1873; application filed September 27, 1873.

To all whom 'it may concern:

Be it known that I, RAPHAEL M. SELDIS, of the city, county, and State of New York, have invented a new and Improved Building-Block 5 and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing- Figure l represents a vertical section. of my invention. Fig. 2 is a plan or top view of the same. Fig. 3 is a perspective view of one segment of the same.

Similar letters indicate corresponding parts.

This invention relates to a building-block laving the shape of a parallelopipedon, and divided into two or more segments, which tit together by tongues and grooves, or by dowelpins and sockets, in such a manner that when said segments are connected they form a block of considerable size and weight, while each segment can be easily handled and put in position, and by these means a rm and durable buildin g can be constructed with comparatively little expense.

In the drawing, the letter A designates a building-block, which is made, in the shape of a cube or parallelopipedon of clay, cement, china, or any other equivalent material that can be molded in the required form. Each of these blocks is made in four segments, a b c d, each segment being formed as shown in Fig. 3. When these segments are placed together they form a block, as shown in Fig. l. On the sides of said segments are formed tongues e and grooves f,- or, instead. of tongues and grooves, dowel-pins and sockets may be used, so that when said segments are placed together they are held firmly in position. On the outside face of the segment a is formed a tongue, g, and on the outside face of the opposite segment c is formed a groove, h, so that when several blocks are placed side by side, as shown in Fig. 2, the tongue g of one block will iit into the groove hl of the adjoining block, and by these means the several blocks vretain each other mutually in position.

By these means I am enabled to produce blocks of comparatively large size and weight, which, being made in segments, can befreadily handled and put in the required position, and which, when put together, form a wall of great strength, firmness, and durability, being equal in those respects to a wall made of heavy blocks of granite or other equivalent material generally employed for large buildings.

My block can be easily handled by one man, the sections being carried and set in the same manner as ordinary bricks, whereas for the purpose of setting solid blocks of granite in the ordinary way a crane is required for the purpose of hoisting each block, and several men are necessary to place the same in position. m 1

For walls of less strength my blocks can be made each of only two segments, the segments a and d, and also the segments b and c, being made in one piece.

What I claim as new, and desire to secure by Letters Patent, is-

A building-block made in the form of a cube or parallelopipedon, in two or more segments, fitted together by tongues and grooves, or by dowelpins and sockets, with 0r without the tongue g and groove h, substantially in the manner herein shown and described.
